Detailed Description

The prepared conversion. Two shapes live in here, and exactly one of them is active:

is_matrix == TRUE source curves -> matrix -> [clamp in clip primaries -> matrix] -> target curves is_matrix == FALSE one or two cmsHTRANSFORM, with the clamp between them when the conversion clips.

The sentinel encodings the two IOPs used to dispatch on from the outside – isnan(m[0][0]) for "no matrix", lut[c][0] < 0 for "this channel is linear" – are still how the curves are stored, because that is what dt_ioppr_eval_trc() and the OpenCL kernels read. The difference is that they are now read here and by the kernels, not by module logic.
